Early identification of rot is key to stopping major damage and expensive repairs. Understanding what wet rot and dry rot are, what they look like, and how they develop will help you spot the signs early.
We take a look at how to identify different forms of wood rot and what treatment options are available, including DIY treatments, products, and more.
What is wet rot?
Wet rot occurs when wood absorbs excessive moisture, typically from leaks, high humidity, or poor ventilation. The wet conditions provide a breeding ground for fungi, which feed on the wood, breaking it down and causing the timber to decay. Wet rot is generally confined to areas that are consistently damp, such as basements, bathrooms, or roof spaces.
The first step in treating wet rot is identifying it. So, what does wet rot look like? Wet rot typically appears as dark, discoloured patches on the affected wood. The wood might feel spongy to the touch, and you may notice a musty smell. In some cases, the wood might start to crumble or develop cracks, leaving behind a soft, spongy texture. If the rot is more serious, you may also notice the paint or wallpaper peeling away as the timber beneath becomes weak and unstable.
Mould and mildew growth
These can harm air quality and trigger health issues, especially respiratory problems.
Damage to walls and plaster
Damp can lead to bubbling paint, peeling wallpaper, and deterioration of wall materials.
Structural weakening
Persistent moisture can weaken a building’s structure, which may lead to costly repairs in the long run.
Can wet rot be treated?
Yes, wet rot can be treated effectively if caught early enough. The key is to remove the moisture source, which is usually what causes the rot in the first place. Once the moisture is removed and proper ventilation is arranged, you can begin treating the affected wood.
Wet rot treatment generally involves removing the rotted wood and replacing it, along with applying a special wet rot treatment product to prevent further damage. However, this should not be done without first addressing the moisture issues, or else the rot will return.
How do you treat wet rot on wood?
Treating wet rot on wood involves several steps.
Here’s a general guide on how to proceed:
- Identify the source of moisture: Before you can treat the rot, it’s important to find and fix the moisture problem. This could be a leaking pipe, a blocked gutter, or poor ventilation. Make sure the area is completely dry before beginning treatment.
- Remove the affected wood: If the wood has become severely rotted, you may need to remove the damaged timber. Cut away all of the soft, decayed material and discard it.
- Apply wet rot treatment products: Once the area is dry and the affected wood has been removed, you can treat the remaining wood with a wet rot treatment product. These treatments usually come in the form of sprays or liquids and work by penetrating the wood and killing the fungi that cause the rot. Some products also help to strengthen the wood by reinforcing it with a protective layer.
- Replace the wood: After treating the wood, replace any sections that were removed. New timber should be treated to prevent future rot.
- Monitor the area: Finally, keep an eye on the area over the coming weeks and months to make sure that the problem doesn’t return. If you notice further signs of rot, you may need to repeat the treatment process.
Wet rot treatment DIY
For minor cases of wet rot, there are several DIY treatment options available. These can help you tackle the issue before it becomes a bigger problem. Many people go for wet rot treatment sprays or products that are easy to apply and highly effective. A wet rot treatment spray, for instance, is often applied directly to the affected wood. It works by killing the fungus and preventing further spread.
There are also wet rot treatment products that are designed to get deep into the wood, offering long-lasting protection. You can apply these treatments using a brush or spray, and some products even come with a built-in fungicide to prevent the rot from coming back. If you feel that the wet rot has developed beyond a minor instance it is important to get it checked.
Schedule Your Free Property Survey Now!
Wet rot survey and property survey
If you’re unsure whether wet rot is affecting your home, it might be time to consider a wet rot survey. A professional surveyor can inspect your property and assess the extent of the rot, recommending treatment options if necessary. Many damp surveyors will also check for dry rot, as the two conditions can often occur together.
A thorough survey can save you from expensive repairs down the line and help stop the spread of the rot. It’s always a good idea to get a survey done if you notice any signs of dampness or rotting timber in your home.
What is dry rot?
Dry rot, unlike wet rot, happens when wood is exposed to moisture and becomes decayed without the presence of water. Dry rot is caused by a specific type of fungus, Serpula lacrymans, which thrives in humid environments. Dry rot can spread quickly, often through timber in walls, floors, and roofs, and it can cause serious structural damage.
So, what does dry rot look like? Dry rot tends to appear as fine, white or grey strands or thread-like growths on timber. Over time, these strands develop into a deep brown or red colour, indicating that the wood has started to decay. The affected wood may feel dry, brittle, and crumbly, and it will often break easily when pressure is applied. A musty, damp smell is also a telltale sign of dry rot.
Dry rot treatment
When it comes to treating dry rot, the first step is to remove any infected wood and assess the extent of the damage. The area should be thoroughly dried out, as dry rot will not thrive in a dry environment. Once the affected timber is removed, treat the remaining wood with a dry rot treatment product.
There are a variety of dry rot treatment products available, such as dry rot wood hardeners, sprays, and injections. These products work by killing the fungus and reinforcing the wood, preventing the rot from spreading. In some cases, it might also be necessary to replace the timber entirely, particularly if the rot has caused serious structural damage.
Dry rot repair
If you’re dealing with a dry rot problem, it’s important to repair the affected wood as soon as possible. This can involve replacing the damaged timber, applying a dry rot wood filler to fill any gaps, or using a wood hardener to strengthen weakened timber. If the dry rot has spread to other areas, you may need to replace a larger portion of the affected structure.
Dry rot treatment costs can vary depending on the extent of the damage. For minor cases, DIY treatments may be sufficient, but for more severe cases, you may need to hire a specialist to carry out the repairs and treatments.
How to repair dry rotted wood
Repairing dry rotted wood can be a tricky job, but it is possible with the right approach. Begin by removing any decayed wood and cleaning the area thoroughly. If you have a small area of dry rot, you may be able to treat it with a wood hardener or filler. For larger sections of rotted wood, it may be necessary to replace the timber entirely.
Once you’ve removed the decayed wood, you can apply a dry rot treatment, such as a dry rot wood hardener, which will help to preserve the integrity of the remaining wood. If needed, replace the rotted sections with new timber, and make sure it’s treated with a dry rot prevention product.
Is dry rot dangerous?
Dry rot can be dangerous if left untreated. It weakens the timber in your home, and over time, this can threaten the actual structure of the building. In severe cases, dry rot can lead to collapsed floors, ceilings, or walls, which can be expensive and dangerous. If you suspect dry rot in your property, it’s vital to address it quickly before it spreads further.
Keep your home clear of rot
Wet rot and dry rot are serious problems that can cause real damage to your property if not dealt with early. Identifying the signs of rot early – whether wet or dry – will save you time and money in repairs. If you notice discoloured wood, a musty smell, or crumbling timber, it’s important to take action immediately. Whether you opt for DIY treatments or consult with a professional, treating the rot as soon as possible is key to maintaining the health of your property.
